clear array from values

[mister_v]

Hi,

have an array in PHP, and I want to clear all values.
Actually empty it. Like it is new.

you can set it to null

Code: Select all

$foo = null;

or re-initialize it:

Code: Select all

 $foo = array();

Or if you don't need it anymore,
you can "destroy" it:

Code: Select all

unset($foo);

PHP will clean up its memory
(when it needs to. I don't think it does it immediately)

Thanks, I'll test it
